inches (5 cm) between the mounds of cookie dough. Press the dough flat with the
back of a fork that has been dipped in granulated white sugar. Bake the cookies for
about 10 - 12 minutes, or until the cookies are lightly browned around the edges. Cool
completely on a wire rack.
Filling: In the bowl of your electric mixer (or with a hand mixer), beat the
softened cream cheese, peanut butter, vanilla extract, sugar, and melted
chocolate until smooth.
Assemble: Take one
peanut butter cookie and spread about 1 tablespoon of the filling on the flat
side of the cookie. Top with a second cookie, flat side down, to make a
sandwich. If not serving right away, cover and store in the refrigerator. Bring
to room temperature before serving.
